Adds AnimationContainer, which can be used to group a set of

animations to have the same timer. By default each animation has one
animationcontainer, but I'm going to change the tab renderer to share
the animationcontainer so that the pulse effects happen in unison.

Also updated the BoundsAnimator so that I can use it by the TabStrip.

BUG=none
TEST=none
